Only used a handful times. As new. Bought it to use on track but now sold track bike. Label says small which is wrong. Think it is an x large as i am 6 foot 7. Measures approx 54cm from top to bottom. Has a velcro kidney belt and 2 over the shoulder straps. Paid £100 but will accept £70. Work all round north london area so may be able to organise meeting somewhere for viewing/trying on. Give me a call on 07957 427298 (i dont bite!)
cheers, Dan.
